Separation and quantitative determination of y-glutamyl-amino acids has been performed by reaction with a mixture of 2,2,3,3,3-pentafluoro-1-propanol and pentafluoropropionic anhydride followed by gas chromatography (379). 

Fluorinated alcohols—2,2,2-trifluoroethanol and 2,2,2,3,3-pentafluoro-propanol, (both at 2.5 x 10 M) — were much more efficient than the corresponding hydrogenated alcohols in reducing the value of the vibronic ratio R observed by addition of P CD [112]. In presence of y-CD, both types of alcohols have the same efiect on R. The calculated association constants (2 1 complexation was found for P-CD and 1 1 for y-CD) were as much as three orders of magnitude higher than the value in pure water for P-CD, while no appreciable effect was found for y-CD, as reported in Table 3. 

Alternatively, extract exchanged into 2-propanol derivatized with pentafluoro-benzyl bromide derivative dissolved in hexane fractionated over silica gel eluted with 15% toluene in hexane and determined by GC-ECD.

A rapid, automated procedure for single-step and simultaneous extraction of cocaine and 11 related compounds was developed by Lewis et al. [95]. Fluid and tissue specimens were extracted using an automated SPE system (Zymark Rapid-Trace) with a Bond Elute-Certify I cartridge. Samples were derivatized with pentafluoro-propionic anhydride/2,2,3,3,3-pentafluoro-l-propanol prior to GC-MS analysis. The method allowed differentiation between smoking crack and intranasal/intravenous cocaine use and was able to elucidate whether ethanol and cocaine were used simultaneously. Another way to determine cocaine in biological matrices is to measure its metabolites and/or degradation products. MEG is produced when... 

Trifluoromethylpyridazines of type S could be prepared starting from 2-amino-1,1,l-trifluoro-3-phenylsulfonyl-2-propanol (93H(35)909). Compounds of type 6 are conveniently accessible by cyclisation of l,l,l,2,2-pentafluoro-3,4-alkanedione 4-diaIkylhydrazones [93TL(34)5135J. 3-(Trifluoromethyl)-4-pyri-dazinecarboxylates of type 7 have been obtained upon reaction of 2-(alkylamino)-3-(trifluoroacetyl)butenedioates with substituted hydrazines (93JHC(30)1501. ...
